                                    GError **error);

Copies or moves messages from one folder to another. If the `source` and `destination` folders have the same parent_store, this may be more efficient than using `camel_folder_append_message_sync()`.

#### Parameters

source | the source CamelFolder |
message_uids | message UIDs in `source` |
destination | the destination CamelFolder |
delete_originals | whether or not to delete the original messages |
transferred_uids | if non-`NULL`, the UIDs of the resulting messages in `destination` will be stored here, if known. |
cancellable | optional GCancellable object, or `NULL` |
error | return location for a GError, or `NULL` |

#### Returns

`TRUE` on success, `FALSE` on failure

### camel_folder_transfer_messages_to ()

    void

                                       GPtrArray *message_uids,
                                       CamelFolder *destination,
                                       gboolean delete_originals,
                                       gint io_priority,
                                       GCancellable *cancellable,
                                       GAsyncReadyCallback callback,
                                       gpointer user_data);

Asynchronously copies or moves messages from one folder to another. If the `source` or `destination` folders have the same parent store, this may be more efficient than using `camel_folder_append_message()`.

When the operation is finished, `callback` will be called. You can then call `camel_folder_transfer_messages_to_finish()` to get the result of the operation.

#### Parameters

source | the source CamelFolder |
message_uids | message UIDs in `source` |
destination | the destination CamelFolder |
delete_originals | whether or not to delete the original messages |
io_priority | the I/O priority of the request |
cancellable | optional GCancellable object, or `NULL` |
callback | a GAsyncReadyCallback to call when the request is satisfied |
user_data | data to pass to the callback function |
